市场上主要开关品牌一般选用PC料，PC料又叫防弹胶，抗冲击、耐高温、不易变色的特性对于控制电气的开关来说很重要。比较好的开关正面面板和背面的底座都是用PC料的，而一般的开关会在底座上用黑色的尼龙料替换PC料，这样成本就能降低很多
同样用PC料，很多开关厂家用的是海内产的（就算标用的是美国GE什么的其实也是海内合作厂做的，只是由GE卖而已），而目前国内其实还没有一家公司有能力生产PC料，所谓国内产的一般都是用回料重新加工出来的，因而杂质比较高，会很脆，耐热性也明显不佳。较差的开关为降低成本正面面板都可能不用PC料，用混合料或ABS替代。这些材料不仅抗冲击、耐热性差，还容易变色、表面摸多了就显得很毛糙。就是开关过程中导电零件的接触点。触点一要看大小（越大越好），二要看材料。触点目前主要有三种，银镍合金、银镉合金和纯银。银镍合金是目前比较理想的触点材料，导电性能、硬度比较好，也不容易氧化生锈。银镉合金触点其他方面也都比较好，但就是镉元素属于重金属，一方面对人体有害，另一方面和银的融合性也不太理想，会在触点表面形成镉金属小颗粒，导电时可能拉出电弧。纯银做触点其实并不合适，导电性能的确不错，但纯银质地比较软、还很容易氧化（像银首饰时间一长就会变黑）。质地软，开关多了触点就变形了；氧化生锈的话导电性能会差很多，锈点还容易发热，很容易就把触点烧化了。现在主要都是大面板式的，外观和手感都比以前拇指式的要好。拇指式的最大的问题在于容易卡住，因为力矩比较短，开关动作幅度比较小，弹簧轻微软一点或过硬一点，都可能造成开关卡住。前两天看到格雷（别跟我说它是米国的，它要是米国的那我就是火星人）出了个所谓复位开关，试试手感暴涩，拆开一看里面是一个小滚轮，按一下转1/4圈，为减少不可避免的摩擦，上面涂满了润滑油。试想半年后里面润滑油干了，这个开关该怎么用啊。
